BUILDING BLOCK AND WALL CONSTRUCTION Henry W. Haaker, Yonkers, N. Y., assignor of one-half to Joseph Leer, Bronx, N. Y.

Application January 23,1941, Serial No. 375,688

8 Claims. (Cl. 'l2-38) This invention comprehends abuilding wall Y blocks of the wall construction, in addition to effectively sealing the joint therebetween on the outer face of the wall with a view of definitely excluding moisture and frost therefrom.

Morespeoiflcally stated, the invention contemplates the use of a sealing key designed to completely cover the joint between adjacent blocks of the wall, and associated with said blocks in a no vel and unique manner, with a view of maintaining an effective seal against the entrance of moisture at the joint between the blocks.

Another important object of the invention resides in the construction and design of the respective building blocks, whereby the sealing keys for the joints therebetween are effectively maintained in proper association with the adjacent blocks of the wall without requiring the use of auxiliary retaining means for this purpose.

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals of reference indicate similar -parts in the several views and'wherein:

Figure 1 is a fragmentary elevation partly in section of a wall constructed in accordance with the present invention.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a sectional view on line 3-3 of Figure 1.

- Figure 4 is a perspective view of one building blocks.

Figure 5 is a similar view of one of the sealing keys. n

' Referring to the drawings in detail Av indicates a fragmentary portion of a wall constructed in accordance with the presentinvention, and composed'of a plurality of identically constructed building blocks indicated generally at B. These of the blocks may of course be constructed from any suitable material, finished or surfacedin any suitable manner, and also may vary in size witho ut departing from the scope of the invention.

Each block is preferably of the outline illustrated in `Figure 4, and if desired may be provided with any number of vertical air spaces I ll of any cross sectional contour. Depending from the front lower edge of each block is a flange i2, the purpose of which will be hereinafter described. The ends of each block are also formed with vertical channels Il co-extensive with the heighth thereof. The outer face of each block at the ends thereof is further provided with vertical recesses i3, the corresponding edges i4 of which are tapered or inclined as clearly illustrated. By virtue of the construction of these blocks, it is manifest that a wall possessing moistureproof qualities can be quickly and economically built, because the time, labor and cement required is reduced to a-minimum.

In building a wall in accordance with the presentl invention, the blocks B will of course be arranged in superimposed tiers, the lowermostl tier being supported upon a suitable foundation as shown. As the adjacent blocks of each tier are arranged in end to end contacting engagement, the corresponding vertical channels il of these blocks unitedly define passages adapted to receive concrete il or the like by means of which the blocks are sealed and joined together. In addition to this, the corresponding tapered recesses i3 of the adjacent blocks unitedly define tapered pockets to accommodate sealing keys i5 preferably of the contour shown in Figure 5.

These sealing keys consist o f substantially v-shaped plates, the opposed inclined edges i6 of which are adapted to effectively engage the correspondingly tapered edges itl of the blocks B.

By virtue of this construction, it is obvious that the sealing keys I 5 can be readily inserted in their respective pockets, bridging and covering lthe joints between the adjacent blocks of each particular tier, and thereby provide a moistureand frostproof wall construction.

` noted that these tapered pockets open at the upper edge of each block to permit ready inser'- It win be vouter face of each block having tapered recesses ing from each block in overlapping engagement minimum of time and effort. In other words, the

i construction of the wall does not require the it understood that I do not limit myself to what is herein illustrated or described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is:

l. In a wall, identically constructedvbuilding blocks disposed in superimposed tiers and in end to end relation, means providing a cement joint between the ends of the adjacent blocks, separable sealing keys wholly covering the abutting ends of the adjacent blocks on the outer face of the Wall, and means depending from the blocks of one tier and arranged in overlapping engagement with the blocks in the next lower tier and the sealing keys therefor.

2. In a wall, identically constructed building blocks disposed in superimposed tiers and in end lto end relation, means providing a cement joint between the ends of the adjacent blocks, vertically disposed separable sealing keys wholly covering the abutting ends of adjacent blocks on the outer face of the wall, and a flange depending from each block and arranged in overlapping engagement with the corresponding block in the next lower tier and said covering means therefor.

3. In a wall, identically constructed building blocks disposed in superimposed tiers and in end to end relation, means providing a cement joint between the ends of adjacent blocks, separable sealing keys vertically supported by the adjacent with adjacent blocks of the next lower tier and bridging said sealing key.

5. In a. wall, building blocks disposed in superimposed tiers and'in end to end relation, means joining the ends oi adjacent blocks, the outer face of each block having tapered recesses at the ends thereof, whereby said recesses of adjacent blocks unitedly define a wedge-shaped pocketI opening at the upper edges of said blocks, a correspondingly shaped sealing key slidably received by said pocket and wholly covering the abutting ends of the adjacent blocks on the outer face of the wall, and a flange depending from each block in overlapping engagement with adjacent blocks of the next lower tier and the sealing key therefor.

6. In a wall, building blocks disposed in superimposed tiers and in end to end relation, means joining the ends of adjacent blocks, the outer face of each block having tapered recesses at the ends thereof, whereby said recesses of adjacent blocks unitedly define a tapered pocket opening at the upper edges of said blocks, a correspondingly shaped sealing key slidably received by said pocket and covering the abutting ends of the adjacent blocks on the outer face of the wall, each key having inclined ledges effectively engaging the tapered edges of the pocket under slight pressure from the weight vof the adjacent block of the next upper tier.

7. In a wall, building blocks disposed in superimposed tiers and in end to end relation, means joining the ends of adjacent blocks, the outer face of each block having tapered'recesses at the ends thereof, whereby said recesses of adjacent blocks unitedly dene a tapered pocket, a correspondingly shaped sealing keyy snugly fitted in said pocket and wholly covering the abutting ends of adjacent blocks on the outer face of the wall, and means on a vertically adje zent block to overlap the key to keep it in position. v

8. In a wall, building blocks disposed in superimposed tiers and in end to end relation, means joining the ends of adjacent blocks, the outer face of each block having tapered recesses at the ends thereof, whereby said recesses of adjacent blocks unitedly define a tapered pocket, a sealing key slidably received by said pocket and wholly covering the abutting ends of adjacent blocks on the outer face of thewall, and a flange on each block engageable with the key of a pair of adjacent blocks to keep the key in position.
